Insulation keeps heat in during winter and out in summer, saving energy costs and increasing comfort. It also helps extend the life of heating and cooling equipment by reducing the workload required to maintain an even temperature throughout your home.

The Department of Energy recommends a minimum R-value for your area, but the exact type and thickness you choose will depend on your budget and DIY preferences. Some types of insulation can be installed by homeowners, notably blankets or materials that can be poured (although liquid foam materials require professional installation). Other types of attic insulation—notably blown-in cellulose, fiberglass batts, and spray foam—are best left to professionals due to the safety precautions they must take during the installation process and the potential for moisture damage to existing structures in your home.

Choosing the Right Type and R-Value

Home insulation is made of a material that resists heat transfer, providing a high R-value per inch. Some of the most common insulating materials are fiberglass, cellulose, and mineral wool. Fiberglass is inexpensive and durable, but it has a lower R-value than other types. Cellulose is made from recycled paper products treated with fire retardants and can be blown into attics and wall cavities. It offers a higher R-value but may lose some of its effectiveness over time, and it can be messy and difficult to install properly.

Spray foam insulation is a chemical-based, closed-cell form that acts as an air barrier and offers a superior R-value per inch. It can be sprayed directly onto attic surfaces, sealing gaps and cracks, but it is expensive and best left to professionals due to the potential for moisture damage.
